cpython - Is it possible to use stackless python 2.7.2 with pythondotnet? -

-
platform: windows 7 assume 32bit versions of both. my current understanding is not possible since both installation processes involve replacing python.exe itself. i guess source each have merged in order functionality both? stackless python: http://zope.stackless.com/ python .net: http://pythonnet.github.io/ we using python .net on ironpython since want access full range of cpython libraries (e.g. matplotlib among others). as state - no, not possible: "merging source" of both projects non-trivial task, well. however, sicne have problem handled stackless, i'd suggest write part of project need stackless python written in it, , part of project, needs .net use regular ironpython - can comunicate data between 2 parts of program using xmlrpc (or jsonrpc) calls -- not complicated thing in python, , work in both python flavors (example here: http://code.activestate.com/recipes/81549-a-simple-xml-rpc-server/ )

php - Check domain validity with wildcard resolver -

-
i have site record links user-provided web pages. want record them if valid. i using checkdnsrr($domain, 'a') check domain validity, , noticed returning true . i'm on shared hosting (so can't change anything). reported bug server admin, , replied: we use opendns our resolvers on servers. resolvers return ip/dns record invalid domains have wildcard set point invalid domains default ip. because of domains enter show having record. okay then. i want avoid using curl on invalid domain waste, there bigger problem. believe resolver returns kind of error page "this domain not exist," , emits 200 or other supposedly valid return status. use status confirm page indeed valid, invalid domain recorded valid site. (humorously, valid domain invalid url leads page emitting 404 or other error status not recorded). anyway, there other way check domain validity? don't mind using third party site. opendns (and others this) return same ip

i'm looking similar in sql server: select top n ties tablename i know limit in postgresql, equivalent of above exist? i'm curious save query each time me. if have table numbers attribute nums : {10, 9, 8, 8, 2} . want like: select nums numbers order nums desc limit *with ties* 3 it should return {10, 9, 8, 8} because takes top 3 plus 8 since ties other one. there no with ties clause in postgresql there in sql server . in postgresql substitute top n ties .. order <something> : with cte ( select *, rank() on (order <something>) rnk tbl ) select * cte rnk <= n; to clear, rank() right, dense_rank() wrong (return many rows). consider quote sql server docs (from link above): for example, if expression set 5 2 additional rows match values of order columns in row 5, result set contain 7 rows. the job of with ties include peers of last row in top n defined order by clause. rank() gives exact same result.

iphone - Mac-address changed -

-
i'm facing problem here, using library uidevice uniqueidentifier ios 5 generate unique identifier ios device, simple md5 hash of mac address. , ok, i've published app in appstore, , after time i've decided write small update. app uses dedicated server api, identifying user important. when started app after update (i integrating tapjoy) - had mac address, , other unique identifier. thought mac address cannot change, wrong? same keeps happening in simulator , on device. yeah, figured out. tapjoy. library implements [[uidevice currentdevice] macadress] method. also, uidevice uniqueidentifer ios 5 implements same method. difference between them - colons in mac address. tapjoy implementation doesn't have them, when uniqueidentifier does. , when use both of libraries @ same time, can cause issues. warned! did, renaming method [[uidevice currentdevice] macadress] in uniqueidentifier lib, [[uidevice currentdevice] macadress_colons] , did trick.
